I see a lot of complaining about not being able to find a fight and they say it increases as the player count lowers. I personally never have a problem finding a fight, but here is an idea that may funnel fighting and force countries to work together.
At set player counts, you could have a set number of bases along the fighting fronts that can be captured. As the player count increases, more bases along the front could be captured. The country with the least amount of players would dictate how many bases (less than the other countries) that could be captured. A higher player count of a country would have more bases that the enemy could capture. A base with an enemy CV near it could be captured. Then only another base close to that base would be become available for capture once the other was captured unless it was along the fighting front. The dynamics would change the game somewhat, but it would force players to fight in smaller areas if the player count is low. All bases stay enabled and can be porked, but just can't be captured unless they are one of the enabled bases along the fighting front. You could even factor in the amount of enemy bases a country owns to make it more focused with less choices.
Just a crazy idea I had, soooooooooo fire away. I have an extremely tough skin.
